DEPL — Any mapping in XML is too verbose

The current mapping for the Any type in the PSM for CCM for XML
(section 9.5.4, page 117 in ptc/03-07-08) is very verbose, for
example an execution parameter property looks like

<execParameter>
<name>entrypoint</name>
<value>
<type>
<simple>
<type>string</type>
</simple>
</type>
<value>
<value>
<value>main</value>
</value>
</value>
</value>
</execParameter>

While not quite "broken," the mapping could be simplified - and
made less intimidating to those who prefer looking at XML code in
a text editor - by not separating the DataType from the DataValue,
but by combining them. An updated UML diagram for a better mapping
of the Any type is attached - it would eliminate the DataValue
type. By including an "Opaque" element of "base64Binary" type,
this mapping includes a potential resolution for 5993.

According to this updated mapping, the execution parameter above
would look like

<execParameter>
<name>entrypoint</name>
<value>
<simple>
<type>string</type>
<value>main</value>
</simple>
</value>
</execParameter>
